To all wwm it may concern.'

Be it known that l, NATHAN M. Lowna, a citizen of the United States, and resident of Pittsburgh,`county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in `Locomotive- Tenders, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

rthe invention relates to locomotive tenders of the type in which there is provided a fuel bin having a sloping back wall, and a fuel carrying deck back of this wall and above the tank.

The object of the invention is to provide improved means for advancing the fuel from the deck to the bin; and one embodiment of the invention is hereinafter described and is illustrated in the accompanying drawings, in which-l Figure 1 is detail plan view of a tender;

Fig. 2 is a detail vertical longitudinal section thereof, partly in elevation; and

- Fig, 3 is a detail section on the line 3-3 of Fig.- 2.

The licor of the fuel bin of the tender is shown at 10, and its sloping rear wall at 11.

The fuel deck 12 Vextends back from theV upper end of the sloping wall or slope sheet 11, and a rear wall 13 rises from this deck. rl`he side walls 1li, l5, of the bin extend back along the deck.

A reciprocating motor 16 is mounted at the upper end of the slope sheet 11 and, as shown, extends above the forward end of the deck. The piston rod of the motor extends downwardly parallel with the slope sheet, and at its forward end is attached to a fuel pusher 17 adapted to move the fuel down-` wardly to the bottom of the bin. A pusher 18 is hinged to the pusher 17, and extends forwardly and is adapted to advance the fuel over the floor of the bin within reach of the fireman without requiring him to leave the locomotive cab. This arrangement of motor and bin pushers is not novel, and the details of construction are not fully illustrated for this reason.

Upon the deck 12 there is mounted a reciprocating fuel pusher 19, which is connected to the motor 16 by means of rigid links 20, .21. As shown, this connection of the links with the motor is through the pusher 17, which is provided with upstanding lugs 22 at its rearward end to which the links `swinging plate 25 adapted, on the forward movement of the pusher, to assume an upright position and thus increase the width of the front face and, upon the recession of the pusher, to fold downwardly in order that it may pass freely under the mass of fuel remaining on the deck. The plate 25 is at- 'tached to the pusher wall by means of pin hinges 26, and the hinge elements which are secured to the pusher front are provided with forwardly projecting stop fingers 27 for limiting thedownward movement of the plate 25. `Brackets 28, 29, vsecured to the front wall 23 of the pusher, provide means `for the pivotal attachment thereto of the links 20, 21. .el pair of supplemental pushers 30, 31, may be mounted `in advance of the pusher 19 and hinged thereto, as shown at 32, 83. These pushers may also be provided with swinging plates 34 at their forward ends, similar to the plate 25.

When the fireman has exhausted the supply of fuel at the forward end of the bin, he starts the motor 16, the valve 35 being placed within convenient reach to enable him to do so, and the lower stratum of coal in the bin is moved forwardly to the shoveling platform, the remaining mass settling down upon the slope sheet, and at the same time the lower stratum of fuel on the deck is moved forward into the bin. Upon the backstroke of the motor the several pushers move backwardly under the superposed mass of fuel, their sloping rear ends facilitating this movement, and the fuel falling in front of them is advanced by the next stroke of the motor. By the mechanism shown the fireman may, without leavingthe cab, advance substantially all of the fuel carried by the tender to the forward end of the fuel bin.

The various pushers may be as wide as may be found desirable. mWhen made considerably narrower than the width of the tender, as shown, they will reduce the load as completely as good practice warrants, before recoaling.

.Preferably guideways 36, 37, are provided on the floor of the deck 12 for preventing lateral displacement of the deck pushers. As shown, these ways are formed of Z-bars having one flange secured to the deck floor and the other fiange projecting inwardly. Angle bars 38, 39, attached to the sides of the pusher 19, project under the instanding flange of the Z-bars and hold the pushei down so that on its backward travel it will pass under all of the fuel.

I claim as my invention- 1. InV combination, a v locomotive tender having a fuel bin provided with a sloping rear wall and a fuel deck back of the bin, a reciprocating motor having its axis parallel with the sloping wall, a fuel pusher reciprocable over the deck, and a rigid link connecting the pusher with the motor.

2. In combination, a locomotive tender having a fuel bin provided with a sloping rear wall and a fuel deck back. of the bin, a reciprocating motor having its axis parallel with the sloping wall, a fuel lpusher reciprocable over the deck and a `rigid bowed link connecting the pusher with the motor.

Y 3. In combination, a locomotive tender having a fuel bin provided with a sloping rear wall and a fuel deck back of the bin, a reciprocating motor having its axis parallel with the sloping wall, a fuel pusher actuated by the motor and movable over the sloping wall, a fuel pusher reciprocableV over the deck, and a rigid link connecting the pusher with the motor. v

Copies of this patent may be obtained for reciprocating motor having its axis parallel with the sloping wall, a fuel pusher reciprocable over the deck and having a forwardly reciprocating motor having its axis parallel with the sloping wall, a fuel pusher reciprocable over the deck, a rigid link connecting the pusher with the motor, and a supplemental pusher in advance of the named pusher and hingedV thereto.

6. In combination, a locomotive tender having a fuel bin provided with a sloping rear wall and a fuel deck back of the bin, a reciprocating motor having its axis parallel with the sloping wall, a fuel pusher reciprocable over the deck, a rigid link connecting the pusher with the motor, and guideways on the deck for preventing lateral and. upward displacement of the pusher,
